What's this?

Im

I don't have periods; I have the implant and I'm on the pill along side. I got diagnosed with CIN1 (pre-cancerous cells in the cervix) and whenever i have sex or an orgasm I bleed. I haven't had sex since last week and I've just gone to the toilet and when I wiped there was this? Any ideas on what it could be? I have a docs appointment on Thursday so I will most likely bring this up with them then but I just want to try and put my mind at rest incase it's nothing serious
